Specification of Letters Patent.

Application filed March 31, 1911. Serial No. 618,098.

PatentedNov.18,1913.

To all whom it may concern Be it known that I, AUGUST Itosniv'ri-mn, a citizen of the United States, residing in West Allis, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Self-Feeders, of which the following is a description, refer-. ence being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in self feeders and more particularly to that type used in connection with corn huskers, threshing machines and clover hullers.

It is one of theobjects of this invention to provide a self feeder which is adapted to cut the bands and feed bundles ofcorn stalks to husking rolls of corn husking and shredding machines or to feed material to'the reducing mechanism of any like machine such as threshing'machines and clover hullers.

A further object of the invention isto provide a self feeder, with means for providing a steady even feed of material to the husking rolls and whichwill prevent the machine from becoming choked'or inoperative when an excess amount of material is fed to the machine: A

A further objectof "the invention is to provide a self feeder of the vibratory and oscillating type in which material is moved forwardly by'a'vibrating table operating in conjunctionwithan oscillating member and is then acted upon by a band cutterand material retarder and is further engaged by a beater if the material is not grasped by the husking rolls of the machine of which the feeder forms a part.

With the above,'and other objects in view, the inventionconsists of the self feeder and its parts and combinations as set forth in the claims.

In the accompanying drawing in which the same reference characters indicate the same parts in the several views: Figure 1 is a central longitudinal sectional view of'the improved self feeder shown in connection 7 with a fragmentary portion of a corn husk ing and shredding machine; and Fig. 2 is a transverse sectional view thereof taken on line 2+2 of Fig. 1.

Referring to thedrawing the numeral 5 indicates a fragment of a corn husking and shredding machine to which the improved feeder 6 is connected. The husking machine is provided with the usual husking rolls 7 (only one of which is shown) having the usual husking and snapping means formed thereon. ,The'frame of the feeder consists of side members 8 having upper outwardly flaring portions 9 to guide the material on to the oscillating table or vibrating bottom portion 10 suspended between the side members 8. The inner end of the bottom portion is pivotally supported on the bail 11 depending from the frame 5 and the outer end is supported on the upper ends of the rock levers 12 (only one being shown) which are carried by the work shaft 13 extending transversely across the machine from one side member to the other. Connecting rods 14 connected to the lower ends of the rock levers 12 extend forwardly therefrom and at their inner ends are carried by the cranked portion of thecrank shaft 15 journaled in the frame 5. These connecting rods are provided with upstanding plates 16 which extend through elongated slots 17 provided in the bottom'portion 10 and have saw teeth or serrations 18 formed on their upper edges which extend forwardly in the direction of the feed. The bottom portion 10 is also provided with similar toothed plates 19 which, are positioned on opposite sides of and spaced a distance from the connecting rod plates. Thesebottom plates extend approximately the full length of the bottom portion and are adapted to move the material into the path of movement of the connecting rod plates whichwill move the material to the husking rolls or other reducing mechanism.

A kicker hood 20 provided with rearwardly extending toothed plates 2l is pivotally suspended, from a rod 22rcarried by upstanding arms 23 pivoted to the sides of the frame 8. The inner end of this hood is carried byithe cranked portion of the crank shaft 2-4 which extends transversely across the machine and is journaled in hearings on the frame 8. The hood also carries band cutters 25 anda medial partition 26 which plays between the double walls 27 of the bottom portion medial partition 28. These part1- tions serve to divide the feed space into two parts and are only used in connection with a machine having four pairs of husking rolls. The hood is oscillated in a direction opposite tothe feed of the material and its functions are to cut the bands and to kick back excess material and prevent clogging;

A. shaft'30 positioned above the upper ends of the bushing rolls and at a short distance from the hood is provided with beater knives 31 forming a beater 32 which is adapted to engage the material and pull it toward the husking rolls. The-beater rotates in the opposite direction with relation to the direction of rotation of the hood shaft so that the material carried forward by the vibrating table and the oscillating bars and in part retarded V b the hood will be en a ed se arated and moved toward the husking rolls by the form of angle plates which serve to prevent the material from winding closely around theholding plates 3d of the beater.

The shafts 15, 24 and are provided with pulleys 35, 36, and 37 respectively anda belt 38 engaging said pulleys and e-Xinding to a source of motion serves to rotate said shafts and the parts connected thereto in the desi e d ti n In the operation of the feeder, bundles of material are thrown on the Vibrating bottom portion of the feeder 'and the bundles will be moved forwardly by the vibration of the bottom portion and the oscillation of the bar plates into engagement with the band cutters of the hood. 'lhe material will then pass beneath the hood to the husking rolls or other mechanism and beengaged thereby. If an excess amount of material is fed to the feeder the kicker hood will retard the excess ameunt and if all of the material passing beneath the hood is not immediately grasped by the husking rolls the beater knives will engage it and again present it to the rolls until engaged. If any of the bands should escapefbeing cut by the band cutters they will be engaged and cut by the beater knives.

From the foregoing description it will be seen that the feeder is slmple in construction 'andhoperation and is well adapted to perform the functions desired. WVhat I claim as myinvention is:

l. A self feeder, comprising atwo-part oscillating table for initially moving material, an oscillating member positioned above the oscillating table for engaging and retarding a portion of the material moved therebeneath, and another member positioned to engage the material passed, between the oscillating table and the oscillating member and to further move said material. r
